When using this Python idiom, it is customary to uses “kwargs” as the parameter name as a helpful hint to what is going on.
Since the challenge is passing in a single dictionary as a positional argument, using the kwargs-type placeholder fails because it is not expecting positional arguments.
If you were to use *info to accept any number of positional arguments then the dictionary passed in would be placed into a list named info as the first element. For comparison, the following code would pass:
def favorite_food(*info):
return "Hi, I'm {name} and I love to eat {food}!".format(**info[0])
